Bunsen Burner (Pack of Two)

Product Code : SCL-CL-12010

The Bunsen Burner (Pack of Two) is a pair of high-temperature ambient gas burners used for heating, sterilizing, and combustion during laboratory experiments. Designed for chemistry teachers, physics students, and laboratory technicians, this setup provides an adjustable, localized open flame to ensure efficient thermal reactions across diverse scientific workflows.

Product Description

The Bunsen Burner (Pack of Two) from Science Lab Supplies is engineered to deliver reliable open-flame thermal energy for standard laboratory tasks. Manufactured with a heavy-duty, die-cast zinc alloy base and a durable nickel-plated brass mixing tube, this burner configuration prevents tipping and resists corrosion under prolonged exposure to heat and chemical spills.

Each unit features a precision-machined brass needle valve and a rotating aluminum air collar sleeve. These components allow operators to fine-tune the fuel-to-air balance, ensuring easy transitions between a cool luminous flame and a hot, clean-burning blue flame. This pack provides an exceptional value upgrade for busy high school science departments, university research centers, and industrial testing facilities that rely on robust heating instruments for day-to-day operations.

Key Features

• Heavy Die-Cast Base: Equipped with an expanded, weighted base profile to ensure high operational stability and prevent accidental tipping.
• Dual Adjustability: Features a knurled needle valve for gas flow regulation and a rotatable sleeve collar for precise oxygen ratio tuning.
• Premium Material Build: Built with a nickel-plated brass burner tube that resists oxidation, flaking, and structural heat degradation.
• Serrated Inlet Tube: Features a factory-formed, ribbed brass inlet connector to secure flexible gas tubing tightly without gas leaks.
• High Thermal Output: Capable of reaching extreme flame temperatures up to 1200°C for demanding chemical reduction assays.
• Universal Lab Compatibility: Seamlessly fits beneath standard lab tripods and works efficiently alongside premium laboratory glassware setups.

Technical Specifications

What's Included in the Kit

• 2 x Premium Bunsen Burner Units
• 2 x Threaded Brass Gas Needle Valves
• 2 x Adjustable Aluminum Air Sleeves
• 1 x Gas Type Calibration Guide and Safety Manual

Applications / Uses

• Heating chemical reagents and solvent solutions during qualitative analytical chemistry tasks.
• Sterilizing microbial loops, culture plates, and glass instruments in clinical biology workspaces.
• Serving as a baseline, high-temperature heat source inside advanced physics and chemistry science kits.
• Executing flame test analyses to identify metallic cations by color emission spectra.
• Bending, sealing, and drawing out glass tubing sections for custom experimental assemblies.

How to Use the Bunsen Burner (Pack of Two)

1. Inspect both burner units to ensure the mixing tubes are clear of dust and the serrated inlets are free of blockages.
2. Connect a certified, heat-resistant rubber or neoprene gas hose firmly onto the serrated inlet tube.
3. Close the air collar completely by rotating it until the air ventilation holes are fully covered.
4. Turn on the main gas source supply valve and immediately introduce a spark or long lighter over the top of the burner tube.
5. Adjust the bottom needle valve to set the flame height, then open the air collar slowly to introduce oxygen until a sharp, distinct blue inner cone forms.

Safety Note: Never leave an active, open-flame burner unattended. Always shut off the main gas line valve first rather than relying solely on the needle valve to extinguish the unit.

Care & Maintenance

• Orifice Verification: Clear out internal gas orifices periodically using a fine wire pin to prevent carbon scaling or dust blockages.
• Residue Removal: Wipe down the nickel-plated brass tube with a damp cloth after it cools completely to clean away spilled chemical salts.
• Dry Storage: Store the burners upright in a low-humidity cabinet to prevent moisture accumulation inside the gas pathways.

Frequently Asked Questions

What is a Bunsen Burner (Pack of Two) used for?

It is used to supply a continuous, adjustable open flame for heating chemicals, boiling solutions, and sterilizing biological equipment. This pack contains two complete burners, making it ideal for multi-station student benches or industrial testing lines.

What type of gas does this burner require?

This standard model is factory-calibrated for natural gas systems, though specialized variants for Liquefied Petroleum Gas (LPG/Propane) can be selected depending on your facility's utility setup.

Can the flame temperature be adjusted?

Yes, by rotating the aluminum air collar, you control the volume of oxygen entering the tube, allowing you to switch between a low-heat yellow flame and a high-intensity blue flame reaching up to 1200°C.

Is this burner set safe for middle and high schools?

Absolutely, the burners are constructed with weighted, extra-wide anti-tip bases and secure serrated hose connections, which drastically minimizes the safety hazards associated with classroom lab activities.

What hose size is needed to connect the burner?

The serrated brass gas inlet connector is designed to fit standard 8 mm (approximately 5/16 inch) inner diameter flexible laboratory gas tubing securely.
